UV CURABLE-TYPE RELEASE COATING OLIGOMER

摘要

PURPOSE: Provided is a UV curable-type release coating oligomer, which has mainly acrylic groups to completely control its UV cure and is economically advantageous over silicone compound. CONSTITUTION: The UV curable-type release coating oligomer is represented by formula I, wherein Y is O or NH group and Z is a residue of a compound of formula III, IV or V, except a leaving group(H); and is prepared by reacting a compound of formula II having many isocyanate groups with a compound of formula III: R1-CH2OH or formula IV having a UV curable group and optionally a compound of formula V having a releasing group. The UV curable-type release coating oligomer of formula I having 1 or 2 of UV curable groups and the UV curable-type functional acrylic oligomer of formula I having 3 of UV curable groups are combined with a multifunctional acrylate monomer, a photoinitiator and any additives to prepare a UV curable-type release coating agent.
